Normal PIN Signal, with cc1101

Projects Programming
1

hello,

a question,

with a cc1101 433mhz module, can I transmit a normal pin signal, without sending data or a buffer or anything?

would love to see your answer.

Greetings, Anne Schepers

what is a "normal pin signal"? isn't the "SI" pin driven by a digital output that's either 1/0?

if you're connecting it to an Arduino Serial output, i believe the output is HIGH until something is transmitted and start bit is made LOW.

oh sorry, I mean can you just use an analogWrite/digitalWrite signal to turn the cc1101 on or off, or do you really need to pass data?

as mentioned, "SI" is a digital input and supports frequency shift keying (FSK) so a 1/0 modulates the carrier frequency between 2 frequencies.

analogWrite() generates a PWM signal which is also binary.

seems like you're trying to find a uses for a transceiver. as mentioned, you could connect a spare Arduino Serial interface to it

Sound like you are talking about modulation mode "2-FSK" (Binary Frequency Shift Keying).
